Gaze behaviours, situation awareness and cognitive workload of air traffic controllers in radar screen monitoring tasks with varying task complexity

International Journal of Occupational Safety and Ergonomics, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 12

Published: Feb. 11, 2025

Objectives. Air traffic controllers should maintain high situational awareness (SA) and low cognitive workload to ensure aviation safety. However, increased task complexity may influence air controllers' SA workload. Meanwhile, eye-tracking provides insights into the gaze patterns that might signify SA. This article investigates behaviours, of different radar screen monitoring tasks with varying complexity. Methods. Twenty-eight participants performed three tasks, including call-sign association, position identification heading projection. Cognitive were evaluated for each using National Aeronautics Space Administration load index (NASA-TLX) global assessment technique (SAGAT), respectively. The Gaussian mixture model was used cluster high/low. Eye-tracking reveals behaviours contribute formation. Results. significantly differ between levels While has a significant main effect on fixations human operators, it does not pupil diameter. Conclusions. Fixation-related metrics changes in under complexity, while side effects be mitigated.

A study of dynamic functional connectivity changes in flight trainees based on a triple network model

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: March 6, 2025

The time-varying functional connectivity of the Central Executive Network (CEN), Default Mode (DMN), and Salience (SN) in flight trainees during a resting state was investigated using dynamic network (dFNC). study included 39 37 age- sex-matched healthy controls. Resting-state fMRI data behavioral test outcomes were obtained from both groups. Independent component analysis (ICA), sliding window, K-means clustering approaches utilized for evaluating (FNC) temporal metrics based on triple networks. Correlation analyses performed assessments these metrics. demonstrated significantly enhanced connection linking CEN DMN 2 (P < 0.05, FDR corrected). Additionally, spent less time 5, while they exhibited protracted mean dwell fractional windows 2, which correlated with accuracy Berg Card Sorting Test (BCST) Change Detection (all P 0.05). improved between following completion rigorous training resulted increased stability. This enhancement may be relevant to cognitive abilities such as decision-making, memory, information integration. When multitasking, displayed superior visual processing skills flexibility. dFNC research provides unique perspective sophisticated capabilities that are required high-demand, high-stress occupations piloting, thereby providing significant insights into intricate brain mechanisms inherent domains.
